Description

Laureth-4 is a non-ionic surfactant belonging to the polyoxyethylene lauryl ether family, known for its excellent emulsifying, wetting, and solubilizing properties. This versatile chemical is a critical component in formulations requiring a balance between hydrophilic and lipophilic characteristics. It is essential for manufacturers in the personal care, pharmaceutical, and industrial cleaning sectors seeking reliable and consistent performance in their products.

Application

• Personal Care & Cosmetics: Primary emulsifier and solubilizer in creams, lotions, shampoos, and bath products.
• Pharmaceuticals: Used as an excipient in topical ointments, creams, and as a solubilizing agent for active ingredients.
• Industrial & Institutional Cleaning: Key surfactant in liquid detergents, degreasers, and hard surface cleaners for its grease-cutting and wetting action.
• Textile Processing: Acts as a wetting agent, emulsifier, and dye leveling assistant in various textile treatments.
• Agrochemicals: Employed as an adjuvant in pesticide and herbicide formulations to enhance spreading and penetration.
• Metal Working Fluids: Functions as an emulsifier and lubricity agent in soluble oils and coolants.
